[FlyRotary] Re: Performance coatings- bearing
damage?
When I
first started flying my coot the rotors were not coated and I was
fighting cooling problems and I was seeing oil temps up to 260 degrees
on full power climb and cruising at 220 degrees, I then pulled the
engine down and coated the rotors without pulling the bearings and had
no problems with them.
After coating
the rotors the temp toped out at 220 on climb and dropped to 180 in
cruise, at that point that was the only change I made and ran it for
several hundred hrs so that should be a good comparison of apples to
apples, since then I have made changes that has dropped the temp to
160 on climb and 140 in cruise.

This
is just the sort of testimonial that I was looking for Ken.
Thanks very much. I think I'll go ahead with plan A, and have
them coated. If the bearings look damaged when they return, I'll
come up with some way to change them. I should have them in the
next few days, and should be able to get them to Performance Coatings
in time for their next Wednesday run.
Thanks,
Rusty
(now if someone could just tell my installers how my new Trane
heat pump is supposed to be wired)
It probably wouldn't be as pronounced of a temp change if
your cooling system was real efficient which my early system was not,
if the temp going into the oil is greater than the temp going out the
temp will just keep climbing which was my case so the ceramic coating
cut the in going temp to less than outgoing temp so the drop was
drastic.
